Gateways without Power Supply
Note
The gateways without integrated power supply unit need an additional power supply
module (bus refreshing module) which feeds the gateway an the connected I/O
modules.
Power Distribution Modules
The power supply for gateways and I/O modules is fed to the power distribution modules;
therefore, it is not necessary to supply each individual module with a separate voltage.
Electronics Modules (Standard Product Line)
The standard electronics modules contain the I/O-functions of the BL20 modules (power
distribution modules, digital and analog input/output modules, and technology modules).
They are plugged onto the base modules and are not directly connected to the wiring and can
be plugged or pulled when the station is being commissioned or for maintenance purposes,
without having to disconnect the field wiring from the base modules.
